Abstract
This study examined the link between theory of mind (ToM) in middle childhood and teachers’ propensity for mental-state language and self-reported conversational-instruction strategies. Multilevel analyses on 430 Italian children (221 girls, Mage = 9.34 years, SD = .63, Range: 7.95–11.43 years) from 27 primary-school classrooms and their teachers showed that: (i) there were striking between-classroom differences in children’s ToM; (ii) teachers’ propensity for mental-state language (β = .14) and self-reported conversational-instruction strategies (β = .16) were uniquely associated with pupils’ ToM even when child-related (i.e., age, verbal ability, number of siblings and SES) and teacher-related variables (i.e., ToM, verbal ability and years of experience) were controlled; and (iii) the association between self-reported conversational-instruction strategies and ToM was significant in older children and smaller classrooms. These findings extend socio-cultural accounts of ToM by showing a developmental continuity of environmental effects on children’s ToM.
